During the sub-process of extracting/ skidding, the tree lengths are moved from the trail (buffer 22) to the forest road (buffer 32).
Usually, the extracting is executed mechanically. Often used machines are the cable skidder and clam-bunk skidder. In both cases, the transport of the tree lengths is carried out in a dragging movement. The cable skidder can also be used not only for the skidding of tree lengths but also for the combined sub-processes of pre-skidding and skidding (see “Solutions for pre-skidding and skidding of tree lengths”).
